. martin, good morning. >> reporter: good morning, lynn. israel's army warned of dangerous days ahead. difficult days ahead. and they're already difficult enough. today israel is continuing its attacks on gaza, still targeting hamas militant leaders and in particular over the last 12, 16 hours attacking stockpiles of long range rockets that hamas has been building up in gaza. that's what israel says this is tack is all about. stopping hamas from the ability to attack israel with the rockets. they say they destroyed many of the long range rockets which can target cities as far north as tel aviv. there is one report from gaza that the palestinians had fired a rocket at tel aviv but there is no confirmation of that. there was no news of it landing. one missile did get to the anti-rocket defense system and killed three israelis who apparently did not obey instructions to seek shelter but were looking at the action from their balcony. the army is telling everybody in israel, do what you're told and then you'll stay safe. inside gaza, at least 13 palestinians have been killed, 100 wounded.
